I'd be inclined to agree with that assessment. The US version had been slated to be on the NBC network, which is one of the four major broadcasters in the US, and moving it to IFC, which is a small-viewership basic cable channel that most people are unfamilar with, is not impossible, but it doesn't make much sense. If you hear something about it being sold to the USA network, that would be a likely move; some of NBC's second-tier/niche programming goes there.
